As I breed as well, I start my puppies off with house training on puppypads/newspaper at 4 weeks, also teach them about not snatching food, handling them, cleaning them with baby wipes and brushing them, so its nothing out of the ordinary when they go to their new homes.
The ones that stay learn about walking next to me with a collar and lead trailing behind them, as soon as they can go out they go walks to the little park at the bottom of the road, learn to sit at the kerb etc. We start proper training class at about 12 weeks, by then they know the basics.
